Radon and Thoron concentration of soil gas was measured by Scintrex Radon detector RDA 200 in the
Rajabasa geothermal field, South Lampung regency, Indonesia. This study is aimed todeterminethe buried fault
zoneunder theoverburdenlayer. The survey areacovers three geothermal manifestations in the southern part of
Rajabasageothermalfield. The result indicates fault system trending SW-NE (N 60o
E) and SSW-NNE (N 8o
E). The
contour map of Radon concentration performed high value in the three manifestations which was included survey area;
those are 123 cpm in Gunung Botak hot spring, 145 cpm in Kunjir fumarole and 382 cpm about 300 m from Bulakan
(Way Belerang) fumarole. Three manifestations were connected by two fault. The first fault passed begin from Gunung
Botak directed to Kunjir and the other across the first fault from SSW to Bulakan. The contour map of Radon and
Thoron ratio indicated that the second fault system is not only indicate the presence of the fault /fracture zones but also
show the extension of the faults/fractures from the depth to the surface.
